How can I get SQL Server column definition with parentheses and everything?

select column_type = data_type +
    case
    	when data_type like '%text' then ''
    	when data_type like '%char' and character_maximum_length = -1 then '(max)'
    	when character_maximum_length is not null then '(' + convert(varchar(10), character_maximum_length) + ')'
    	when data_type = 'numeric' then '(' + convert(varchar(10), isnull(numeric_precision, 18)) + ', ' +
    		convert(varchar(10), isnull(numeric_scale, 0)) + ')'
    	else ''
    end
